C57BL/6 mice are resistant to C3H mouse mammary tumor virus (MMTV)-induced mammary tumorigenesis and lack major histocompatibility complex class II I-E molecules that are essential for presentation of C3H superantigen to T cells. T cells are needed for transmission of milk-borne MMTV from the gut to the mammary gland. In this report, we show that infectious C3H MMTV is produced by C57BL/6 mice that nurse on C3H mothers but that virus production in the mammary gland is delayed compared with that in I-E+ mouse strains.
C57BL/6小鼠对C3H小鼠乳腺肿瘤病毒(MMTV)诱导的乳腺肿瘤发生具有抗性,并且缺乏主要组织相容性复合体II类I-E分子,而该分子对于将C3H超抗原呈递给T细胞至关重要。T细胞是乳汁传播的MMTV从肠道传递到乳腺所必需的。在本报告中,我们表明,由C3H母鼠哺育的C57BL/6小鼠会产生具有传染性的C3H MMTV,但与I-E+小鼠品系相比,乳腺中的病毒产生会延迟。
